The putdata Function

You should not modify the BitsPerSample, InputRange, SensorRange, and UnitsRange properties after calling putdata. If these properties are modified, all data is deleted from the data acquisition engine. If you add a channel after calling putdata, then all data will be deleted from the buffer.
